Two Storey Additions

Reach new heights without moving out.

A Second Storey Addition made easy

With more than 40 years’ experience, Summit's renovation team is renowned for a seamless second storey extension which will give your home a new lease on life.

Our game-changing building processes take your home to an amazing new level, super-fast. 

There is the option to build your second storey extension either via traditional onsite building methods or in our purpose-built, all weather proof factory located here in Myaree.  The choice is yours. 

Whether you are looking to extend and build a parents' retreat, a children's wing or the ultimate entertainment zone, Summit has a range of spacious two storey designs to help get you started.


Meet the Bartlett family

Discover how a second storey extension gave the Bartlett family the space they needed, while still retaining the heritage style of their Fremantle home. 

They were looking for someone to manage the renovation from start to finish and a designer who understood their vision. 

Needless to say, the Barlett family couldn't be happier with their renovation.

The only way is up

Tired of living in the crowded confines of a one level home, or perhaps you want to capitalise on those sweeping tree top or river views?

Maybe it’s time to increase your living space for a growing family by adding more bedrooms or a teenager's retreat with a second storey addition. 

Whatever your reason, Summit can make it happen via our effortless and game-changing building processes that take your home to an amazing new level in no time. 

If you choose to add a second storey extension to your home, we can build it in our all weather proof factory.

Once complete, the extension is simply craned into position and secured to your existing home and is free for you to enjoy in a matter of weeks.

Move up without moving out

At Summit, we take the hard work out of the process by offering a free, no obligation meeting with one of our professional Design Consultants.

They will visit your home for a firsthand look at how it works and offer suggestions as to what type of second storey extension could work for you.

We pride ourselves on offering the best design for your budget, lifestyle and style of home.

We also provide a computer generated perspective, floor plan of your new extensions and a fixed price contract with full high quality specifications.

Expert designers

Our experienced Design Consultants can tailor a two storey design to suit your family and lifestyle, all while transforming your home to new heights without moving out.

Our exclusive onsite Extension Process

If you choose to utilise our innovative construction technology, your second storey extension will be built in our all weather proof factory. By combining the strength of engineered steel, with the advanced thermal-properties of MasterWall, we offer a stronger, superior finish. The completed extension is then simply craned into position and secured to your existing home. From there your staircase is installed and all services connected, so you’re free to enjoy the extra space within weeks.

  • Step 1 out of 3


    Comfortably live in your home while we construct your upper floor extension in our purpose built, all-weather facility at our Myaree headquarters. We manufacture our steel frames in our factory which can operate 24 hours a day, and this controlled environment not only ensures the frames are built to exact specifications, but helps reduce the chance of delays.

  • Step 2 out of 3


    Your second storey extension is delivered directly to your door and craned into place in just a few short hours. The key advantage of this method of building is that you can stay living in your home whilst the upper-storey module is being constructed offsite. This is a real financial benefit to homeowners, particularly if they need to rent another property whilst they’re waiting for their home renovation to finish.

  • Step 3 out of 3


    It’s pretty amazing to watch a home transform over such a short period of time because as a homeowner, you can literally leave for work in the morning and come back that evening with a second story all framed up! Then once your staircase and service connections are finished, in a matter of weeks your new home extension is complete.
